2004 Highlander Limited w/3.3L V6-110,000 miles
AC clutch and cooling fan come on when car is off... One morning last week I came out to find the cooling fan running on the car. I unplugged the fan and went to work. Two days later the battery was dead. I charged the battery and the charging light came on the dash. The car runs fine, unless I turn on the heater or AC. I checked the battery and alternator and they are both fine. After checking fuses and other connections I went to put the ground terminal back on and noticed that the AC clutch engaged.
I unplugged the AC compressor and the cooling fan comes on and the battery light stays on. I unplugged the cooling fan relay and the light went off. But, the car won't run for long at idle this way. If the car dies, I hear some inconsistent clicks from the fuel pump and some clicks under the dash to the right of the steering wheel. I am just about at my wits end chasing this issue. Help?
